It seems like we're constantly hearing about promising battery technologies that could ultimately lead to longer battery life, more power, and smaller units, but as of yet, that big breakthrough hasn't occurred. Maybe nanotechnology, which is the current hot topic in the battery innovations field, will prove to be different .

University of California San Diego researchers have developed a method to enhance the capacitance (up to three times) of carbon nanotube (CNT) electrode-based electrochemical capacitors by controllably incorporating extrinsic defects into the CNTs.
“While batteries have large storage capacity, they take a long time to charge; while electrostatic capacitors can charge quickly but typically have limited capacity. However, supercapacitors/electrochemical capacitors incorporate the... Read Full Story
Researchers at the University of Southern California have demonstrated large, functional arrays of transistors made using simple methods from batches of carbon nanotubes that are relatively impure. For the first time someone has shown solution-deposited, purified semiconducting tubes for high-quality transistors,” says John Rogers, professor of materials science and engineering at the University of Illinois at Urbana-Champaign. “The accomplishment is in the integration of several...

Green Ocean Coatings from Advanced Marine Coatings are an environmentally friendly way to make transport by sea more cost-efficient Leverkusen - The Norwegian company Advanced Marine Coatings based in Gamle Fredrikstad specializes in the development of environmentally compatible, heavy-duty anti-corrosion coatings for sea-going vessels. The 'Green Ocean Coating Heavy Duty' coatings are formulated with Baytubes® carbon nanotubes (CNT) from Bayer MaterialScience, which gives them very high... Read Full Story
With all of the technology that is being continuously introduced and used, it would only seem logical in our quest for a green world to apply some of the renewable energy efforts to this spectrum. That is exactly what some scientists are looking into with theirresearch on how nanotechnology can be used with lithium batteries. According to Science News, a report that will be published in International Journal of Nanomanufacturing asserts that "carbon nanotubes can prevent such batteries from... Read Full Story
1. Drexler comments on the Caltech work “Self-assembly of carbon nanotubes into two-dimensional geometries using DNA origami templates”
This achievement is a milestone in framework-directed self assembly of composite nanosystems, a line of development that I’ve argued is a strategic direction in atomically precise fabrication — useful in itself, and as part of a technology platform for further progress. In self-assembling molecular machine systems, carbon nanotubes could serve as... Read Full Story
This is a follow up to a previous report on Rice University using strong acid to process carbon nanotubes on an industrial scale.
MIT Technology Review reports on a new method for assembling carbon nanotubes has been used to create fibers hundreds of meters long. Individual carbon nanotubes are strong, lightweight, and electrically conductive, and could be valuable as, among other things, electrical transmission wires. But aligning masses of the nanotubes into well-ordered... Read Full Story
CHICAGO (Reuters) - In determining the safety of improbably small materials known as nanoparticles, special properties associated with some of the very smallest particles may be the key, scientists said on Sunday. Nanotechnology, the design and manipulation of materials thousands of times smaller than the width of a human hair, has been hailed as a way to make strong, lightweight materials, better cosmetics and even tastier food. But scientists are only starting to look at the impact such... Read Full Story
Scientists from a number of departments at the California Institute of Technology (Caltech) have recently announced the development of a new structure, which combines the “talent” that DNA has for self-assembly with the amazing chemical and physical properties of carbon nanotubes (CNT). The nanoscale electronic devices could be the key element in finally devising a method that would allow for carbon nanotubes to be arranged within a small-scale electronic circuit. “This project is one of...
